TIME—TEMPERATURE STUDIES OF THE INACTIVATION RATE OF BRUCELLA ABORTUS STRAIN 2308 IN MILK*

Abstract

Experimental data relating to the destruction of B. abortus (2308) in milk by heat are presented. It was observed that B. abortus (2308) was killed in 23 minutes at 142.7°F. and in 14 seconds at 161.6°F. when the preheating time was zero. A practical mathematical method for evaluating the lethal effects of the preheating, holding and cooling parts of the heating curve on the organism is discussed.
